LONDON — Once a month, accountant Michael Byrne pulls on his rubber boots and makes his way to a spot on the banks of the River Thames.
He carefully marks out an 11-square foot patch and, with gloved hands, catalogues each bit of plastic he finds, meticulously reporting the data to the environmental group Thames21. On Aug. 20, for example, he and other volunteers found an average of 31 food wrappers, the sticks from 29 cotton swabs, 12 bottle tops and about 100 pieces of small chewed up plastic in each patch.
“We are the data gatherers” who provide evidence of the plastic that’s clogging the world’s rivers and oceans, he said. “We are building up a picture all along the river of what is washing up.”
Public awareness of the problem of plastic waste is swelling after alarming forecasts that there could be more plastic than fish in the oceans by 2050. Plus the shocking images are rolling in: Britain’s Sky News’ campaign against ocean plastic featuring whales bloated by plastic bags; National Geographic’s chilling picture of a seahorse curled around a pink cotton swab, and filmmaker David Attenborough’s documentary “Blue Planet II” footage of sea turtles shrouded in plastic.
